Michigan citizens holding a Concealed Pistol License (CPL) are legally permitted to carry a handgun on their person. A person cannot carry a concealed weapon while under the influence of alcohol or a controlled substance or a combination of both. However, it is illegal to carry a firearm if your BAC is at or above .02% or if you are under the influence of a controlled substance—even if you hold a CPL.
A police officer must have probable cause in order to require someone to submit to chemical analysis. Prior to requiring someone to submit to a chemical test, the officer must inform the individual: 1) has right to refuse, 2) officer may obtain court order requiring that he/she submit 3) refusal may result in suspended or revoked concealed weapon license.
Under MCL 28.425k, a person who has accepted a concealed weapon license consents to implied consent. When you drive on Michigan roadways as a licensed driver, you have given implied consent to submit to chemical testing if a law enforcement officer suspects you of drunk driving. The same is true for Concealed Pistol License holders.
Michigan’s firearms law states that by accepting a CPL, you give consent to submit to a chemical test of your breath, blood, or urine if an officer suspects you of carrying while intoxicated.
If person submits to chemical testing, they may have a similar test done by a person of their choosing. If the person refuses, the officer shall promptly report the refusal to the concealed weapon licensing board. If person submits to a test and any bodily alcohol is found while carrying a concealed weapon, the officer shall promptly report the violation in writing to the licensing board.
If the person is under the influence of alcoholic liquor or a controlled substance or a combination of both or had bodily alcohol content (BAC) of .10 or above:
If BAC is .08 or more but less than .10:
If BAC .02 or more but less than .08:
*Under this statute, a properly licensed person who has any bodily alcohol content may transport that pistol in the locked trunk or if the vehicle does not have a trunk, it may be transported as long as it is unloaded in a locked compartment or container separate from the ammunition or on a vessel if it is unloaded in a locked compartment separate from the ammunition.
